(replying to a very old email as context for the recent discussion). Geoff, it looks like your change from the initially requested "Add the text specified by the script_frag" to "Add the editing commands specified by the script" was not intended as that was not part of the point you were making. IMO, that bug should be revisited to either - address the intent of the initial request where the script being run is the concatenation of the fragments passed to -e and -f with newlines. - or a variant thereof that covers historical implementations, that is same as above except that a fragment can't end in a backslash. Even sed -e '=;#\' -e q doesn't work (doesn't run the = command!) in traditional sed implementation. -- Stephane
